In 2018, intense rainfall from August 1 had stuffed up the dams and a recent spell of torrential rainfall led to the simultaneous opening of all main dams on August 15. Water gushing down from Idukki and Idamalayar dams led to the flooding of coastal areas from Aluva. As the ocean was tough the water didn’t drain which aggravated the state of affairs. It was the discharge of water from Kakki – Anathodu reservoir that inundated Chengannur and Aranmula areas. The water had risen as much as the peak of a two-storeyed constructing in these areas leaving a path of demise and destruction.
However, the authorities can breathe simple because the rain has stopped and the ocean is comparatively calm. The plan is to launch water from dams in a phased method and to observe the water stage in downstream areas. The district administration in Ernakulam, Pathanamthitta and Idukki districts have made preparations to observe water stage and to shift folks from low mendacity areas after reviewing the state of affairs.
